The chart below lists each of the cranial nerves and the important functions that can be assessed during neurological exam. The chart does not list all structures innervated by each cranial nerve.

Mnemonics for remembering cranial nerve names and sensory vs. motor are listed below the chart.

Efferent fibers (away from CNS out to periphery)
GSE
= General somatic efferents
GVE = General visceral efferents
SE = Special efferents (innervation of muscles to branchiomeric origin

Afferent fibers (from periphery to CNS)
GSA
= General somatic afferents
GVA = General visceral afferents
SA = Special afferents
